For formal use, the variable can be marked with a "#" symbol -- or "#1", "#2", and so forth -- if multiple variables exist in one sentence.
编译集的主要功能就是要保存符号列表，像命名空间、类型、方法、字段、事件、局部变量以及标签等等。
The compilation’s primary role is to hold the list of symbols such as namespaces, types, methods, fields, events, local variables, and labels.
但是理解任何内核的最关键要素是内核的映射，它提供符号信息(比如函数、变量以及它们的地址)。
But an important element of understanding any kernel is the map of the kernel, which provides symbol information (such as functions and variables as well as their addresses).
接下来，需确保您的原子变量使用ATOMIC_INIT符号常量进行了初始化。
Next, you ensure that your atomic variable is initialized using the ATOMIC_INIT symbolic constant.
符号是前面有冒号(：)的任何变量，更妙的是符号本身也是对象！
A symbol is any variable that is preceded by a colon (:), and what's even neater is that symbols themselves are objects!
在编写配置文件时，变量都以百分比符号(%)开始，表示未知的信息。
Variables begin with a percent symbol (%) and stand in for information that can't be known when the configuration file was written.
如果解析后的上下文变量内容为空，则不会发生替换，并且变量名称在查询字符串中保持不变(包括“%”符号)。
If the resolved context variable content is null, no replacement occurs and the variable name remains unchanged in the query string (including the "%" signs).
$somevar 可以对美元符号进行转义，避免在设置提示符的命令中对该变量进行解释，而是在显示提示符时对其进行解释。
The phrase \$somevar escapes the dollar sign, avoiding interpretation of the variable in the command where the prompt is set. Instead, the interpretation occurs whenever the prompt is drawn.
您可能已经看到，XQuery中通过在标识符前加上美元符号（$）来定义变量。
You've already seen in XQuery that a variable is defined by putting a dollar sign ($) in front of an identifier name.
在下一个例子中，我们也会利用这一功能，将一个复合名的顺序编号的符号作为输出环境变量来address。
For the next example, we also make use of the capability to ADDRESS the sequential numbered symbols of a compound name as an output environment.
然而，您可以将复杂的过程置于一个脚本，或者一个程序中，并且传递各种转换符号作为变量到这个脚本或者程序中。
However, you can put complex processing into a script, or even in a program, and pass various conversion symbols as arguments to the script or program. For example.
与jQuery中使用美元符号函数获取上下文变量不同的是，在Prototype中需要使用Event . element函数。
Unlike jQuery, where you simply use the dollar function to get the context variable, in Prototype you need to use the Event.element function.
要实现这种功能，我们可以在yyltype类型的全局变量yylloc中提供这个符号的确切位置。
To do this, provide exact token locations in the global variable yylloc of type YYLTYPE.
其种类很多，但基本的理念是在变量名的开始添加一个标记以表示其类型（例如，所有无符号长型变量都以ul 开头）。
There are lots of flavors of this, but the basic idea is that you put a tag at the beginning of a variable name saying what type it is. (So all unsigned long variables begin with ul, etc.)
在本书中，我们将采用第二种声明风格：将符号* 紧贴着指针变量名放置。
In this book we use the second style and place the * with the pointer variable name.
变量名必须从一个字母开始，因此Velocity很容易把变量名与模板中的货币符号分开（比如， $100不可能是一个变量名）。
Variable names must begin with a letter, which makes it easy for Velocity to distinguish variable names from currency notation within a template (for instance, $100 cannot be a variable name).
宇宙基本常数，比如电磁力强度之类的精细结构常数，符号位“alpha ”，它们因为被假定为不变量而得名。
Fundamental constants such as the strength of the electromagnetic force - the so-called fine-structure constant, or alpha - get their name from the fact that they are supposedly the same everywhere.
上下文是简单的变量和表达式所需的函数，将返回一个值，并且赋值给标识，包括在符号表中的。
A context is simply the variables and functions that are needed by the expression to return a value, and are assigned to the identified included inside the Symbol Table.
符号表记录了程序员声明的所有变量和函数名，以及它们在内存中的地址。
The symbol table holds all the variable and function names made up by the programmer, along with the addresses where they can be found in memory.
执行函数时会为局部变量引入一个新的符号表。
The execution of a function introduces a new symbol table used for the local variables of the function.
这是一份关于地图符号视觉变量的问卷调查。
This is a questionnaire on the variable visual symbols of map.
讨论了计算机学科学术论文中的常量、变量、参数和函数的符号编排规范化问题。
The editing and composing standardization of symbols of constants, variables, parameters and functions is discussed in computer science papers.
OBJECT表示该符号和一个数据对象相关，比如一个变量、一个数组等。
STT_OBJECT The symbol is associated with a data object, such as a variable, an array, etc.
若元件加一斜向直线箭头、则是可变量的符号，表示其排量和压力是可调节的。
If the part adds a diagonal straight line arrow, is the variable mark, indicated that its displacement and the pressure are may adjust.
若元件加一斜向直线箭头、则是可变量的符号，表示其排量和压力是可调节的。
If the part adds a diagonal straight line arrow, is the variable mark, indicated that its displacement and the pressure are may adjust.
